Teledyne Paradise PowerMAX N+1 Phase Combined Amplifier System

The Paradise Datacom PowerMAX system maintains complete parallel redundancy down to the embedded control level. Therefore the loss of an entire HPA chassis will not interrupt remote communications with the system. Remote communications can be either RS485 or Ethernet. The system will automatically correct its gain level in the event of one or more HPA chassis failures.

The PowerMAX system maintains complete parallel redundancy down to the embedded control level. Therefore the loss of an entire HPA chassis will not interrupt remote communications with the system. Remote communications can be either RS485 or Ethernet. The system will automatically correct its gain level in the event of one or more HPA chassis failures.

The sophisticated system monitor and control allows the system to be locally or remotely operated as if it were a “single” chassis amplifier. The system control maintains a hierarchical management that allows the operator to interface to a single chassis of the multi-module array.

Another feature unique to Paradise Datacom’s PowerMAX is the introduction of “true rms” output power measurement. Unlike other amplifier systems that utilize diode detection schemes, the PowerMAX reports the true rms output power of the system independent of the number of carriers and modulation schemes.

Proprietary waveguide combining techniques are employed so that maximum power combining efficiency is optimized within the operating frequency band.

System Output Power and Configurations

Because the system power combining is purely passive and no switching is used, there is never an interruption in RF output power. The PowerMAX system is typically used as a “self-redundant” system. The output power is sized such that the loss of (1) RF module’s power will still allow the system to maintain its minimum required output power. This type of system architecture is described as n+1 redundant. The system can be configured with any number of modules but best overall efficiency is obtained with the popular binary combinations of 4, 8, or 16 modules. It is very easy to upgrade the PowerMAX system from 4 modules to 8 or 16 modules in the field. It is not necessary to fully populate the system at the time of initial purchase. This provides the user a path to upgrade output power capability as system requirements grow thus keeping the capital investment minimized. For sizing redundant output power capability use the following guideline to determine the output power of the system with the loss of (1) module.

      4 Module System - 3 of 4 Modules Operable = 2.5 dB loss in output power capability
      8 Module System - 7 of 8 Modules Operable = 1.2 dB loss in output power capability
      16 Module System - 15 of 16 Modules Operable = 0.6 dB loss in output power capability

System Prime Input Power

Proprietary adaptive bias techniques are utilized to achieve an aggressive balance between RF output power and minimized DC input power.

Prime power may be introduced into a terminal block at the top of the cabinet. Electrical conduit is routed between the terminal block and a 5RU boxed assembly, the AC Distribution/Circuit Breaker Panel, which houses a separate toggle switch circuit breaker for each power supply module in the system. Additional circuit breakers are available for auxiliary equipment mounted in the cabinet.

System prime input power is achieved with an array of modular (hot-swap) power supply chassis. Power is distributed from the power supplies to the SSPA modules via a bus rail assembly.

Each of the power supply modules has its own single phase, 180-264 VAC input. This makes it very convenient to parallel the AC inputs of two modules and connect the array to a three phase AC input source.

The power supply chassis is configured as a n+1 redundant, hot swappable power supply. In the event of a power supply module failure, the amplifier system will not fail. The failed module can be changed without ever taking the HPA out of service. The microwave amplifier architecture is also designed for maximum soft fail redundancy.

Prime system AC Input Power specifications are shown on pages 7-9 for various PowerMAX power levels and configurations.

Hitless Redundancy

For mission critical systems in which no power outage can be tolerated, an eight module PowerMAX system can be operated with only four modules installed. In this way, the additional four modules can be installed without requiring the system to be powered off.

The only disadvantage of operating the eight module PowerMAX system with four modules is the additional 3 dB loss that the four module (half-system) system experiences by going through the final hybrid combiner as shown at right. Therefore the overall output power is actually 6 dB below what it would be with all eight modules present in the system.

If, however, the module output power is sized such that this reduction in output power can be tolerated, the system shown at right is an effective means of scaling the system from four to eight modules and maintaining true hitless operation. The system never has to be powered down and there are no mechanical switches involved that would create an interruption of service.

With parallel system architectures, the amplifier output power capability and gain will change as the number of active modules vary. The PowerMAX system is designed with an Auto-Gain Control mode so that the overall system gain will remain constant in the event of a single module failure. See the table below.

SSPA Chassis Population Options

The PowerMAX system is available in a variety of system module configurations and output power levels. The system is based on Paradise Datacom’s 3RU chassis with 100% hot swappable active assemblies. The units can be configured with a wide variety of SSPA frequency bands and power levels, and can be fitted with the following SSPA modules:

  • C Band: 100W, 150W, 200W, 250W, 300W, 400W, 500W and 600W
  • X Band: 250W and 500W
  • Ku Band: 50W, 70W, 100W, 125W, 150W, 200W and 300W
  • Ka Band: 40W and 80W

Optional Cabinet Exhaust System

The PowerMAX system is available with an optional cabinet exhaust system, which includes a rear door for the cabinet and an impeller assembly for each grouping of four (4) SSPA chassis in the system.

Each impeller can produce 5060 CFM of air flow (at 0 inches H2O static pressure) from the cabinet, and draws 7.6 Amps at 230V. Power is provided from the AC Distribution Box to the circuit-interruptible power connectors in the interior of the rear door. Separate power cables connect from the outer door couplers to each impeller.
